11. A method for processing fluids comprising:
delivering a fluid and a plurality of magnetic particles to a plurality of fluid containers;
supplying an electrical signal, directed from an electrical power source to a PCB board, through a plurality of electrical contact terminals included in the PCB board, to a plurality of electromagnets by establishing an electrical connection between spring loaded connections included on each electromagnet and the plurality of electrical contact terminals of the PCB board;
generating an electromagnetic field within at least one of the plurality of the fluid containers using the plurality of electromagnets; and
controlling the electromagnetic field generated by each electromagnet to generate a plurality of magnetic field gradients within the at least one fluid container sufficient to magnetically influence the plurality of magnetic particles within the fluid in each fluid container.
